Application fired November 8,1906'. senti No. 342,523.

To all whom it may concern:l

"wherein an effective support and reinforcing of the service rail ends is secured, while'at the same time preserving a thorough and complete insulation of the joint To this end the invention primarily has in view an insulated joint structure wherein each rail end has a supporting base independent of that for the other rail end, while at the same time the individual support for each rail end isA reinforced throughout the entire length of' the joint. In this connection the invention contemplates an individual and independent metal base support for each rail end which may be so arranged as to be carried upon two ties.

A further object of the invention is to provide a construction which preserves a complete insulation of the entire joint, while at the same time providing a direct metal bearing or base support for the rail ends so that v in the principal forms ofthe invention there is no insulation which is required to carry the load or Weight of the passing trains,

The essential features of the invention are necessarily susceptible to a wide range of structural modification and also capable of application to many varieties of side joint plates,'chairs, angle bars, or splice bars, without departing from the scope of the invention, but for illustrative purposes there are shown 'in the drawings certain practical embodiments of the invention.' Y

In these drawings: Figure l is a sectional perspective view of a rail joint embodying the present invention.

Fig. 3 is a top plan view of the matching shoes, omitting the insulation and bolts and indicating by dotted lines the separate rail ends. Fig. 4 is a sectional view showing another form of rail joint embodying the invention. Figs. 5 and 6 are separated perspective views respectively of the opposite joint shoes, and showing a modification in the formation of the upright members tov preseutflat, vertical abutments for the heads and nuts of the bolts. Fig. 7 is a sectional perspective view illustrating another modified construction of joint embodying the improvements claimed herein. Fig. 8 is a perspective view of the joint shoesshown in the modification of Fig. 7, and illustrating in dotted lines .the insulating end post arrangement. Fig. 9 is a top plan View of the parts shown in Fig. 8, omitting the upper portion of the end post. i

Like references designate corresponding parts in the several figures of the drawings.

A distinctive feature of the present invention is that of providing a divided rail-supporting base comprising separate complemental base plates, each of which constitutes an independent metal supporting base for one rail end. This plan of construction possesses many structural advantages largely on account of each rail end having a separate base plate so designed and so arranged with referenceto the vtrack ties that the rail hascsrest directly upon individual metal base supports without the interposition f base insulation of' any character. It is therefore the purpose of the present invention to embody the divided or two-part base idea in structures meeting all of the necessary structural and engineering requirements of astrong, durable, and effective insulated rail joint.

Referring to that exemplication of the invention shown in Fig. 1 of the drawings, the rail joint proper includes the service rail ends 1 and 2, the oppositely arranged complemental joint shoes 3 and 4, andthe wooden or equivalent filler blocks 5 and (i, respectively interposed between the joint shoes 3 and-4, and the adjacent sides of the rails. ,The joint shoes are arranged respectively at opposite sides of the rails and each consists of an angle plate having an upright member 7, and a horizontal fiat base plate 8 projecting-inwardly from the lower edge of the upright member 7 s so as to lie-beneath a rail base. Though different designs of joint shoes may be employed, yet each shoe 3 and 4 preferably consists of an integral body, in which the upright member or girder 7 is integral with the base member or base plate 8. Atthe outer corner of the shoe, the same may be formed with a continuous rein-I force and spiking flange 9 extending the full length of the shoe. Also, the upright member of each shoe may be arranged at right angles to the base plate member 8 so as to lie in a perpendicular plane and be clamped directly against the outer shoulder faces 10 of the ller blocks 5 and G, Whose inner sides or faces conform to and fit against the sides of the'rrails beneath the rail heads in the manner common tothe filler blocks in the well known Weber types of railjoints. lThe -said flipright member 7 may be properly and ybroadly termed a side joint plate, which plate, for the purposes of the present application, and other co-pending applications, will be understood to be that plate receiving the joint bolts and also carrying a half-length base member or base plate 8. v i

Inx the form of joint being described,'the distance between the side plates 7 of the opposite shoes and i is illustrated as'being greater than the widthof the rail base, and also each base plate 8 is 'shown 'of greater width than the rail base resting thereon. Furthermore, the base plate of each shoe is-of alength approximately equaling one-half the full length of the rail joint inem` bers so that each' base platev receives and supports thereon one rail-end, and,v in order that the support for both rail ends may be alikefthe separate base plates are duplicates in design and arrangemenhfand are located respectively at opposite sides of thefjoint between .the nlree'tingnds of the rails., Inthis connection, it

will be seen that-the opposite shoes'3 ande-are constructed alike, 'though one of said'shoes, designated by j the number 3,.ha's thebase plate 8 projected inwardly from one -end portion thereof only, while the opposite shoe, designatedby the'number 4, has its'base plate -projected inwardly from the correspondingly opposite end portion thereof.

- metal left by the shearing or casting operationl along A he opposite complemental shoes?) 'and 4 are shwp arranged with an intervening space or gap between lthe inner adjacent edges of the separate base plates, whilel the longitudinal edge llof each base plate 8 is arranged in parallellism to` and spaced from the longitudinalv edge 12 of a narrow horizontal gir-der flange 13 projected inwardlyfrom theflower edge of the'side joint plate of the oppositeshoe.y kThis flange is`the por-tion of the that end portion of the shoe or joint plate'which is not provided with a supporting basel* plate for'a'rail end, and forms 4a narrow reinforcing continlatonof,thel base plate 8 of each shoe.

Various insulating, expediente may'be resorted to: Oneof these, as shownlin Fig. lof. thedrawingefrei sides in constructingl each of the opposite 'filler blocks 5 and 6 with a pendent insulating lip 14 projected 'from the bottom side thereof, .and lying between the edges'.

1 1 and 1,2of the opposing base plate and .girderflange below the. filler.' In this construction each filler is 'only provided with a half-lengthinsulating,lip 1 4 along that portion ofthe blockoverlying the interval r site shoe or lj ointl plate.

The end insulation betweenthe adjacent ndedges of the separate base-plates `8 may be provided for by any suitable .or practicalfform of insulation." The air -between a base plate 8 and the fiange 13 on' the* 'oppogap itselffmight, underisome conditions, providesuf- .ficient insulation, but'it is preferable to provide a definite insulation vat that point. This may be `accomplished by utilizing the insulating end post'v l5,

(between the service rail lends), as,4 the insulating .medium,. such use. ofthe end post only requiring the base Vlt'of the end post 15 tobe sufficiently wide to drop into the interval between the adjacentv end edges Y of the separate base` plates 8. This scheme of insula- Yfr@ . \tion is plainly shown in Figs. 8 and -9 ofthe drawings:

vIn'.` the assemlzilingv and fastening up of the joint parts constituting the structure illustrated in Fig: l,

there are employed. the usual yseriesofjoint bolts' 1.7 whose heads and nuts are clamped directly upon/the side joint plates, while ant insulation between the bolts and the' rail webs is secured by having, the rail bolt holes 18 fitted elongated` insulating sleeves 19 projecting beyond both'sides'of 4the rail web`s,'and held.

within openings providedin metallic tension straps 20 arranged upon opposite `sides ofthe webs the rails. To complete this insulation, insulatingstraps lbase support ycarried by two ties.

22 are interposed between the inner faces of the metal tension straps 20 and the adjacent faces of the rail vwfebs. '(See Fig. 1).. v

The 'form ofvjoint just describedk is preferably de signedfor Vuse in connection with a pair of track ties 23 arranged respectively at opposite sides of the verti.-

4cal .plane ofthe joint between the rail ends'. -With such arrangement, each joint shoe or side joint plate` hasa support on both ties7 thus giving each rail end a i In the modification shown in Figs. 4, 5 and '6 the lrail joint as an entirety/is made up of the same general combination and relation of parts as the jointfv shown in Fig. l'of the' drawings, with the prominent lso base plate SO'adapted to `lie beneath and constitute a base lsupport for one of the rail ends, and the separate disposed' jopposi'tefandspaced from .the longitudinal edgesof the narrow girder flanges 31. .The-elements f3() and 31 occupy thesanle relation and preserve ,thel same functions asv the corresponding elements 8 ,and

13, previously described. f

By `reason of the complemental inclined faces of the i filler blocks and the inclinedside joint plates 26, it

4will be obviousthat ,whenv the 'bolts are tightened' the joint shoes will be d rawil or 4lifted in a vertical direction, thereby drawing the metal base vplates 30' into firm contact with the rail bases.

In the modi-cation shownin Fig. 4 of the draw-ings,I Y

the .insulatingend post 15 may be utilized as the insuof the'separate' base plates 30, while forinsulation between 'each base plate and the opposing grder ange, there may be used an insulating strip'32 clamped upon each flange 31 beneath the wooden filler thereover, and., having its pendent ange portion 33 lying 4between the `latingmedium .between the adjacent inner4 end edges elements 30 and 31. Also, the joint bolts 34 may be f passed directly through 'the belt holes 35 in the 'fail j `webs and insulatingbushings 36 interposed between the ',headsl and nuts of the bolts and theadjacent sides of the jointplates 26, andrhaving at one side neck orfcollar,

extensionsl 37 projectinginto the' 'bolt holes in the, said plates.

A modification of this construction is suggested in Figs. 5 and 6 of the drawings, wherein the up-y right members of the shoes are illustrated 'as being formed along their upper' edge portions with reinforce.v

ribs 50 presenting vertical, lflat abutment faces 51 for thehead and-nut parts of the-bolts to be drawnagainst. This obviates the use of bevel washers, or 'the like to provide vertical abutment facesv for the bolts.

Another modification ofthe-invention is shown in joint' is very similarV to the one shown in'Fig. l1 of the drawings and differs'therefmm'principally inthe pai.-

ticulars of showing a modified anangefmento insula :Figs 7, Sand 9 of/thedrawi'ngs.' Thisconstruction of 9ol c -base' plates l30 arearianged in the same horizontal plane in spaced relation with their longitudinal edges apparent to those skilled in tion between each base plate, and the opposingk girder flange of the opposite shoe, and in the reinforcement of the individual shoes themselves. Hence, similar refer-v ence characters are applied to the same joint parts illustrated in the group-ot figures 7, 8, and 9, and in Fig.

1 of the drawings. A Referring to the modified features it will be noted by reference to the said group o i ligures 7, 8, and 9 of the drawings, that each of the joint shoes 3 and 4 may be provided intermediate their ends with pendent reinforcing gird ers 39. The girde'r 390i each shoe projects below the horizontal plane of the base plate'- 8 thereof `and lies between the two ties upon which the joint is supported. Also, in the construction referred to, the' proper insulation between the base plates 8 and the opposing girder flanges 13 is provided for by insulating strips 40, one for each base plate member 8. Each in- Insulation of the modified type of joint shownl in Fig.

7 of the drawings is completed by the end post insulation l5 between the rail ends, as previously referred to,

and by the employment ofA plain insulating bushings or sleeves 42 inserted in the bolt holes of the rail ends.-

Various other modifications of joints of the Weber and other types may b e obviously utilized in connection i .with the special improvements herein emphasized, but

from the foregoing it is thought that the construction, use, and advantages of the several parts' will be readily the art without further de7 scription.
